MSI is fine at the low end with the Neo Series if high overclocks are not a priority, the P43 is a P45 basically, only noticeable difference is OC being limited to around 400~415FSB. Gigabyte is also very good on the low end as is Biostar. The new mid-range ASUS P45 boards are much better than the P35 series they had, they have caught up if not passed Gigabyte now in that $125~$150 range, as has Biostar. I would buy based on the features you need, even ASRock is doing well with the new chipsets now. 😉
